Alarm-driven Data Log Entries
The ACCESS 9340 and 9360 can detect over 50 alarm conditions,
including over/under conditions, digital input changes, phase
unbalance conditions, and more. (See Chapter 6—Basic Alarms on
page71 for more information.) Use WinPM.Net to assign each alarm
condition one or more tasks, including forcing data log entries into
one or more data log files.
For example, assume you have defined three data log files. Using
WinPM.Net, you could select an alarm condition such as “Overcurrent
Phase A” and set up the meter to force data log entries into any of the
three log files each time the alarm condition occurs.
Organizing Data Log Files (ACCESS 9360DC)
You can organize data log files in many ways. One possible way is to
organize log files according to the logging interval. You might also
define a log file for entries forced by alarm conditions. For example,
you could set up three data log files as follows:
NOTE: The same data log file can support both scheduled and alarm-
driven entries.
Data Log 1: Log voltage every minute. Make the file large
enough to hold 60 entries so that you could look
back over the last hour’s voltage readings.
Data Log 2: Log energy once every day. Make the file large
enough to hold 31 entries so that you could look
back over the last month and see daily energy use.
Data Log 3: Report by exception. The report by exception file
contains data log entries that are forced by the
occurrence of an alarm condition. See the previous
section “Alarm-driven Data Log Entries” for more
information.
